The invention claimed is: 1. A crystalline ammonia transition metal molybdate material having the formula: (NH 4 ) 2 .(NH 3 ) x (H 2 O) 2-x MMO y O z where ‘M’ is a metal selected from Mg, Mn, Fe, Co, Ni, Cu, Zn, and mixtures thereof; ‘x’ varies from greater than 0 to 2; ‘y’ varies from 1.5 to 3, z is a number which satisfies the sum of the valences of [(M+y)+2]; the material having a x-ray powder diffraction pattern showing peaks at the d-spacings listed in Table A: TABLE A d(Å) I 0 /I 6.99 m 6.30 w 5.81 vs 5.36 m 5.05 w 4.79 m 4.43 w 4.10 w 3.95 w 3.79 m 3.69 m 3.50 m. 2. The crystalline ammonia transition metal molybdate material of claim 1 wherein the crystalline ammonia transition metal molybdate material is present in a mixture with at least one binder and wherein the mixture comprises up to 25 wt % binder. 3. The crystalline ammonia transition metal molybdate material of claim 2 wherein the binder is selected from the group consisting of silicas, aluminas, and silica-aluminas. 4. The crystalline ammonia transition metal molybdate material of claim 1 wherein M is nickel or cobalt. 5. The crystalline ammonia transition metal molybdate material of claim 1 wherein M is nickel. 6. The crystalline ammonia transition metal molybdate material of claim 1 wherein the crystalline ammonia transition metal molybdate material is sulfided. 7. A method of making a crystalline ammonia transition metal molybdate material having the formula: (NH 4 ) 2 .(NH 3 ) x (H 2 O) 2-x MMO y O z where ‘M’ is a metal selected from Mg, Mn, Fe, Co, Ni, Cu, Zn, and mixtures thereof; ‘x’ varies from greater than 0 to 2; ‘y’ varies from 1.5 to 3, z is a number which satisfies the sum of the valences of [(M+y)+2]; the material having a x-ray powder diffraction pattern showing peaks at the d-spacings listed in Table A: TABLE A d(Å) I 0 /I 6.99 m 6.30 w 5.81 vs 5.36 m 5.05 w 4.79 m 4.43 w 4.10 w 3.95 w 3.79 m 3.69 m 3.50 m the method comprising: (a) forming a reaction mixture containing NH 3 , H 2 O, and sources of M and Mo; (b) adjusting the pH of the reaction mixture to a pH of from about 8 to about 10; and (c) recovering the crystalline ammonia transition metal molybdate material. 8. The method of claim 7 wherein the recovering is by filtration, centrifugation or evaporation of solvent. 9. The method of claim 7 further comprising adding a binder to the recovered crystalline ammonia transition metal molybdate material. 10. The method of claim 9 wherein the binder is selected from the group consisting of aluminas, silicas, and alumina-silicas. 11. The method of claim 7 further comprising sulfiding the recovered crystalline ammonia transition metal molybdate material. 12. A hydroprocessing conversion process comprising contacting a feed with a catalyst at hydroprocessing conversion conditions to give at least one product, the catalyst comprising: a crystalline ammonia transition metal molybdate material having the formula: (NH 4 ) 2 .(NH 3 ) x (H 2 O) 2-x MMO y O z where ‘M’ is a metal selected from Mg, Mn, Fe, Co, Ni, Cu, Zn, and mixtures thereof; ‘x’ varies from greater than 0 to 2; ‘y’ varies from 1.5 to 3, z is a number which satisfies the sum of the valences of [(M+y)+2]; the material having a x-ray powder diffraction pattern showing peaks at the d-spacings listed in Table A: TABLE A d(Å) I 0 /I 6.99 m 6.30 w 5.81 vs 5.36 m 5.05 w 4.79 m 4.43 w 4.10
